Office administrators direct and coordinate the work activities of office workers within an office. They supervise office clerks and other workers in their tasks and plan department activities with other supervisory personnel. Administrators often define job duties and develop training programs for new workers. They evaluate the progress of their clerks and work with upper-management officials to ensure that the office staff meets productivity and quality goals. Office administrators often meet with office personnel to discuss job-related issues or problems, and they are responsible for maintaining a positive office environment. There are more than 1.4 million first-line supervisors of office and administrative support workers in the United States.
